AnimationNodeSub2¶
Inherits: AnimationNodeSync < AnimationNode < Resource < RefCounted < Object
Blends two animations subtractively inside of an AnimationNodeBlendTree.
Description¶
A resource to add to an AnimationNodeBlendTree. Blends two animations subtractively based on the amount value.
This animation node is usually used for pre-calculation to cancel out any extra poses from the animation for the "add" animation source in AnimationNodeAdd2 or AnimationNodeAdd3.
In general, the blend value should be in the [0.0, 1.0] range, but values outside of this range can be used for amplified or inverted animations.
Note: This calculation is different from using a negative value in AnimationNodeAdd2, since the transformation matrices do not satisfy the commutative law. AnimationNodeSub2 multiplies the transformation matrix of the inverted animation from the left side, while negative AnimationNodeAdd2 multiplies it from the right side.
